我遇到了这个问题，我想根据它们的 ID 删除元素。但是，在模态中，它没有得到我要删除的特定 id。相反，它首先获取最低的 ID。例如，如果我删除 id 为 88 的产品，它会先删除它之前的 id，例如 88 之前的数字。如何删除具有正确 id 的特定元素？

<?php
ob_flush();
session_start();
include('includes/header.php'); 
include('includes/navbar.php'); 
if($_SESSION['admin_name']){
    //do nothing
}
else{
echo "<script type='text/javascript'>window.top.location='http://localhost/CarRentalv3/admin/adminlogin.php';</script>"; exit;
}
$admin_name = $_SESSION['admin_name'];
?>

最佳答案

您正在使用 id="delete" 创建按钮在你的 while 循环中。因此，您最终会得到很多具有相同 ID 的按钮，这些按钮都是无效的 html 并会在此处产生问题。

您还可以在 while 循环中打开标签，然后在模式中关闭它。这也将创建无效的 html，因为您将打开很多表单标签并且只关闭其中一个。

没有看到你的 process.php 上的代码请记住，此处的修复并非 100% 能解决您的问题。

首先改变

<td>
    <form action="process.php" method="POST">
    <input type="text" id="id"  readonly value="<?php echo $rows['id'];?> ">
    <button type="button" name="delete" onclick="myFunction();" id="delete" class="btn btn-danger" data-toggle="modal" data-target="#deleteModal">Delete</button>  
</td>

到

<td>
    <button type="button" name="delete" onclick="myFunction('<?php echo $rows['id'];?>');" class="btn btn-danger" data-toggle="modal" data-target="#deleteModal">Delete</button>  
</td>

然后改变你的功能

function myFunction(print_value) {
  document.getElementById("print").value = print_value;
}

最后改变你的模态主体

<form action="process.php" method="POST">
    <label>PIN</label>  
    <input type="text" id="print" readonly  >
    <input type="password" name="pin" id="password" class="form-control" />  
    <br />  
    <button type="submit" name="delete_btn" id="pin_button" class="btn btn-warning">Confirm</button>  
</form>

并删除另一个关闭表单标签 </form>你之前有</tbody>
